The latest invention from Sir James Dyson is the Airblade Tap, a fixture that washes and dries your hands, depending on your movement. Hands in the center and you get water; move them to either side, and cold air blows at 430 mph to speed dry your hands. Dyson says that the faucet dries 15 pairs of hands for the price of one paper towel. Though the fixture currently costs $1,500, so it may not be popping up in your local pub any time soon.
